The first ViewController is managed by a NavigationController, and it has a UIWebView. The WebView modules has click events to push a ViewController in the NavigationController.
But now, the ViewController which is init by code is normal, and which is init by storyboard is abnormal, the navigation bar was disappeared. It only occurs in iOS8 and earlier Version.
PS: The Init Code is like this:
Code:
ViewController *vc = [[ViewController alloc]init];
[self.navigationController pushViewController:vc animated:YES];
Storyboard:
ViewController *vc = [ViewController defaultViewControllerWithStoryboard:#"StoryboardName"];
[self.navigationController pushViewController:vc animated:YES];
Thank You.
MainViewController* presentController = [self.storyboard instantiateViewControllerWithIdentifier:#"StoryBoardidentifier"];
[self.navigationController pushViewController:presentController animated:YES];
if its not working try this Normally yourStoryBoardName is Main:
UIStoryboard* storyBoard = [UIStoryboard storyboardWithName:#"YourStoryBoardName" bundle:nil];
MainViewController* presentController = [storyBoard instantiateViewControllerWithIdentifier:#"StoryBoardIdentifier"];
[self.navigationController pushViewController:presentController animated:YES];

Hi there I used this code to move in to new contorller just with code and without segue .
UIStoryboard * mainstoryb = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
UIViewController * vc = [mainstoryb instantiateViewControllerWithIdentifier:#"online_shop"];
[self presentViewController:vc animated:YES completion:nil];
how do I show Navigation bar or title bar on next view ?
You need to present NavigationController as below :
UIViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:ContactUSVCID];
UINavigationController *objNav = [[UINavigationController alloc] initWithRootViewController:vc];
[self presentViewController:objNav animated:YES completion:nil];
if you want navigation bar, then you have to push not present
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:storyboardName bundle: nil];
SecondViewController * vc = [storyboard instantiateViewControllerWithIdentifier:#"ViewControllerB"];
/********if dont have navigation bar***********/
UINavigationController *initialNavigationController = (UINavigationController*)[self.storyboard instantiateViewControllerWithIdentifier:#"HomeNavCtrl_id"];
[self presentViewController:initialNavigationController animated:YES completion:nil];
/**********else*************/
[[self navigationController] pushViewController:vc animated:YES];
Embed your ViewController in navigation controller and storyboard id to navigation controller then use this code
UINavigationController *initialNavigationController = (UINavigationController*)[self.storyboard instantiateViewControllerWithIdentifier:#"HomeNavCtrl_id"];
[self presentViewController:initialNavigationController animated:YES completion:nil];
If you present a view controller it will always be presented full screen.
Try this
UIStoryboard * mainstoryb = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
UIViewController * vc = [mainstoryb instantiateViewControllerWithIdentifier:#"online_shop"];
[self presentViewController:navigationController animated:YES completion:nil];
I have 5 view controller and want to come back from the last view to 1st view controller
Call a function in which you have to change the app rootviewcontroller. set it as a navigationController
yourViewcontoller *viewController = [[yourViewContoller alloc] init];
UINavigationController *navController=[[UINavigationController alloc]initWithRootViewController:viewController];
self.window.rootViewController = navController;
If you're using storyboards, give the UINavigationController a Storyboard ID. You can then initiate it and present through the code:
UINavigationController *vc = [self.storyboard instantiateViewControllerWithIdentifier:#"<Storyboard ID>"];
[self presentViewController:vc animated:YES completion:nil];
Use this method on Animation splash screen
[self performSelector:#selector(setHidden:) withObject:nil afterDelay:2.0];
-(void) setHidden:(id)sender
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboare" bundle:nil];
YourVC* vController = (YourVC*)[Storyboard instantiateViewControllerWithIdentifier:#"storyboardId"];
UINavigationController *navcotoller=[[UINavigationController alloc]initWithRootViewController:vController];
self.window.rootViewController =navcotoller;
}
If you are using UINavigationController you could and should simply call
[self.navigationController popToRootViewControllerAnimated:YES];
I've got the iPhone working fine with creating a segue programmatically.
e.g.
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard_iPhone"
bundle:nil];
FooBarViewController *foobarViewController = (FooBarViewController *)[storyboard instantiateViewControllerWithIdentifier:#"foobarViewControllerID”];
[self.navigationController pushViewController:foobarViewController animated:YES];
Now I'm trying to do something similar on the iPad storyboard.
The goal being to programmatically change the detail view to a view on the storyboard.
I thought maybe:
[self.splitViewController.navigationController presentViewController:foorbarViewController animated:NO completion:nil];
However this doesn't work. Any suggestions?
I believe I've solved my own question with the following function:
- (void) presentDetailView : (UIViewController *) viewcontroller {
UINavigationController *detailNavCtrl = [[UINavigationController alloc] initWithRootViewController:viewcontroller];
detailNavCtrl.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
detailNavCtrl.modalPresentationStyle = UIModalPresentationOverCurrentContext;
[[[self.splitViewController viewControllers] lastObject] presentViewController:detailNavCtrl animated:NO completion:nil];
}
I want to add a navigationcontroller to an existing viewcontroller which is created using storyboard, i have embed it in a navigation controller, but the code for navigating (shown below) is not working even after embed in the navigation controller:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
EditProfileViewController *nextViewController = [storyboard instantiateViewControllerWithIdentifier:#"EPVController"];
[self.navigationController pushViewController:nextViewController animated:YES];
When i have tried to log self.navigationController, it shows null.
Update: It is fine when i am trying with presentViewcontroller , but i
want to push the viewcontroller with navigationController.
I am struggling with this for two days,Please help.
If self is a subclass of UINavigationController, you do not need to refer to the navigationController property. (Note that this won't work if EditProfileViewController is also a subclass of UINavigationController, as you can't push a UINavigationController inside a UINavigationController).
EditProfileViewController *nextViewController = [storyboard instantiateViewControllerWithIdentifier:#"EPVController"];
[self pushViewController:nextViewController animated:YES];
Otherwise, if you don't have a pre-existing navigation controller
EditProfileViewController *nextViewController = [storyboard instantiateViewControllerWithIdentifier:#"EPVController"];
[self presentViewController:nextViewController animated:YES completion:nil];
I used code from this question Display UIViewController as Popup in iPhone it is working fine but I don't want to use segue or I can say I can't use segue because all the code is created programmatically, so I cant set segue on button.
I used this code but it didn't work
- (IBAction)open:(id)sender {
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
UIViewController *newVC = (UIViewController *)[storyboard instantiateViewControllerWithIdentifier:#"Second"];
[ViewController setPresentationStyleForSelfController:self presentingController:newVC];
[self.navigationController pushViewController:newVC animated:YES];
}
Edit 1:
View after popup
You should check if this VC self.navigationController is not nil. and i think you want to presentViewController: not pushViewController:...
